CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of and priority to Singapore Patent Application No. 10201606866P filed Aug. 17, 2016. The entire disclosure of the above application is incorporated herein by reference.

FIELD

The present disclosure relates broadly, but not exclusively, to methods and systems for authorizing an electronic transaction between entities.

BACKGROUND

This section provides background information related to the present disclosure which is not necessarily prior art.

Authorization is an important aspect of processing an electronic transaction, and involves, among other things, authenticating one or more entities participating in the electronic transaction. During authorization, the one or more entities may be electronically identified as an authorized entity. For example, a customer may be required to present his payment card to a merchant and input his personal identification number (PIN) into the merchant's point-of-sale terminal for authorization of an electronic financial transaction. That is, both the PIN and physical payment card provide means for authenticating and authorizing the customer at the merchant's point-of-sale terminal.

However, payment cards, such as credit cards and debit cards, may be misplaced or stolen, which leaves the cardholder vulnerable to financial theft. Moreover, the cardholder may forget his PIN and as a result is unable to complete the electronic transaction.

Electronic transactions may also include electronic fund transfers between two or more entities. Usually, a recipient's bank name and account number is required for the fund transfer. However, such information may be sensitive and the recipient may be reluctant to share such information. Moreover, the account number typically consists of a string of numbers which may be easily forgotten.

A need therefore exists to provide methods and system for authorizing an electronic transaction between entities that seek to address at least some of the above problems.

SUMMARY

This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features. Aspects and embodiments of the disclosure are set out in the accompanying claims.

The computer program, when loaded and executed on such a computer, effectively results in an apparatus that implements the steps of the preferred method.

FIG. 1 shows a flow chart illustrating a method 100 for authorizing an electronic transaction between two entities, according to an example embodiment. For the sake of brevity, the following description is directed to an electronic transaction between two entities. However, the method 100 is equally suited for electronic transactions between three or more entities without the need for extensive modifications.

The first step 102 of the method 100 involves receiving, at a verification module, coincidentally captured facial image data relating to both of the two entities. The coincidentally captured facial image data includes first captured facial image data relating to a first of the two entities and second captured facial image data relating to a second of the two entities. Preferably, the first and the second captured facial image data are captured at substantially the same time (i.e. coincidentally captured, or captured in parallel). In an implementation, the coincidentally captured facial image data may comprise the first captured facial image data with the second captured facial image data appended thereto. In this format, the coincidentally captured facial image data can be viewed as a single data packet and yet can be easily split into its constituent first and second captured facial image data for purposes which will become apparent below.

The verification module may receive the coincidentally captured facial image data from a mobile device (such as a smartphone or tablet computer) comprising two image capturing modules. The first captured facial image data is captured using a first of the two image capturing modules and the second captured facial image data is captured using a second of the two image capturing modules. In an example scenario, both entities are physically present at the same place and at the same time and facing each other, and the first image capturing module is a “front facing” camera of the mobile device and the second image capturing module is a “back facing” camera of the mobile device. One of the two entities, e.g. the first entity, uses the “front facing” camera of his mobile device to capture a photo of his face and uses the “back facing” camera to take a photo of the second entity that is facing him. In this manner, the mobile device is able to acquire the coincidentally captured facial image data relating to both of the two entities.

The verification module may be in communication with a standalone database that is realized using cloud computing storage modules and/or dedicated servers. The verification module may also have an integrated database. In either case, (i) facial image templates relating to each of the two entities and (ii) account data relating to each of the two entities are enrolled in the database. With reference to Table 1, there are four entities enrolled in the database, each having its respective facial image template, account data and reference geographical location data. Further details on the reference geographical location data will be provided below. It will be appreciated by a person skilled in the art that the facial image data shown in Table 1 is merely for illustrative purposes. In actual implementations, the facial image data is in a format appropriate for the execution of facial recognition techniques, such as those disclosed in Li, Stan Z. and Jain, Anil K., “Handbook of Facial Recognition” (Springer, N.Y., 2011), the entirety of which is incorporated herein by reference.

The facial image template and the account data of each entity are linked in the database. In other words, if a particular facial image template is known (e.g. facial image data “A”), the corresponding linked account data (i.e. account number “01-356-8944”) can be determined. The account data includes, but is not limited to: account number, name of account holder, transaction amount limit, withdrawal amount limit, and bank name. Only the account number is shown in Table 1.

Turning back to FIG. 1, the second step 104 of the method 100 involves using the verification module to authenticate each of the two entities based on a comparison between the coincidentally captured facial image data (received at step 102) and the respective facial image templates relating to each of the two entities that is enrolled in the database. The comparison may include generating a representation of the captured facial image data (e.g., by a feature extraction process), and comparing the generated representation to one or more template representations stored in the database (the template representations having been generated according to the same process as that used to generate the representation of the captured facial image data). A positive authentication corresponds to a substantial match between the coincidentally captured facial image data and corresponding ones of the facial image templates.

The substantial match between the coincidentally captured facial image data and the corresponding ones of the facial image templates can be based on a pre-defined degree of similarity between the first and the second captured facial image data and the corresponding ones of the facial image templates. Since there may be some difference between the captured facial image data and the facial image template (i.e. not a perfect match), the pre-defined degree of similarity provides for a margin of difference. For example, a system administrator can set the degree of similarity to be 90% to accommodate any differences between the captured facial image data and the facial image template, e.g., due to constantly varying ambient lighting conditions where the facial image is captured.

On determining that each of the two entities are positively authenticated at step 104, the third step 106 involves retrieving, from the database, the account data relating to each of the two entities based on the coincidentally captured facial image data. The step 106 of retrieving the account data relating to each of the two entities based on the coincidentally captured facial image data may include the sub-steps of (a) retrieving the account data relating to the first of the two entities that is linked to the facial image template that has a closest similarity with the first captured facial image data; and (b) retrieving the account data relating to the second of the two entities that is linked to the facial image template that has a closest similarity with the second captured facial image data. For example, with reference to Table 1, the first captured facial image data is compared with all the enrolled facial image templates “A” to “D”. If the first captured facial image data has a pre-defined degree of similarity with one of the enrolled facial image templates (e.g. “A”), and the first captured facial image data has a closest similarity to facial image template “A”, the account data (“01-356-8944”) linked to facial image template “A” is retrieved.

The fourth step 108 of the method 100 involves using the verification module to generate an authorization message for authorizing the electronic transaction. The authorization message includes, but may not be limited to, the account data relating to each of the two entities retrieved from the database at step 106.

On the other hand, if at least one of the two entities is not positively authenticated at step 104, the method 100 may further include generating, using the verification module, a decline message for declining the electronic transaction.

In order to maintain a record of transactions to minimize frauds, facilitate chargebacks, etc., the coincidentally captured facial image data relating to both of the two entities received by the verification module at step 102 is stored in the database. In case there are any disputes after the transaction has taken place, the coincidentally captured facial image data can be retrieved to facilitate investigations. For example, if a user alleges that he did not participate in the transaction, the coincidentally captured facial image data relating to both of the two entities can be reviewed to verify the user's assertion.

To supplement the record of transactions, the method 100 may further include receiving, at the verification module, a transaction identifier relating to the authorized electronic transaction. The received transaction identifier is stored in the database, in association with the coincidentally captured facial image data relating to both of the two entities, as shown in Table 2. In this manner, the coincidentally captured facial image data corresponding to a disputed transaction can be easily retrieved. The transaction identifier is preferably a unique identifier relating to each authorized electronic transaction, and may be generated at a transaction module or payment module that is configured to process transactions. The generated transaction identifier may be transmitted by the transaction module/payment module to the verification module.

To further supplement the record of transactions, the method 100 may further include receiving, at the verification module, a time-stamp relating to a date and time of the coincidentally captured facial image data and/or authorized transaction. The time-stamp is stored in the database, in association with the transaction identifier and the coincidentally captured facial image data relating to both of the two entities, as shown in Table 2. The time-stamp can be used to further facilitate investigations of disputed transactions, for example, when a user alleges that he did not participate in the transaction at a specified time. In Table 2, the time-stamp relates to a date and time of the various authorized transactions.

Turning back to Table 1 (rightmost column), besides enrolling the facial image template and account data relating to each of the two entities in the database, reference geographical location data relating to each of the two entities can also be enrolled in the database. The enrolled reference geographical location data is linked to the corresponding ones of the facial image templates.

The enrolled reference geographical location data can be used to facilitate the method 100 for authorizing the electronic transaction. Specifically, the method 100 can further include the sub-steps of (a) receiving, at the verification module, current geographical location data relating to a current location of the first of the two entities; and (b) comparing, using the verification module, the current geographical location data and the reference geographical location data that is linked to the facial image template that has a closest similarity with the first captured facial image data. The authorization message is only generated on determining that there is a substantial match between the current geographical location data and the reference geographical location data that is linked to the facial image template that has the closest similarity with the first captured facial image data. The reference geographical location data and current geographical location data may be one or more of a country, city, state, town, or geographic coordinates.

Continuing from the example above where the captured facial image data of a first entity has a closest similarity to facial image template “A”, now assume that the reference geographical location data that is linked to facial image template “A” is “New York City” and this data is enrolled in the database (see Table 1). The first entity wishes to participate in an electronic transaction with a second entity, and both entities are physically present at the same place in New York City at the same time and facing each other. Besides acquiring the coincidentally captured facial image data relating to both of the two entities, the mobile device (having a suitable location tracking module) is also configured to determine and transmit the current geographical location data to the verification module. If the current geographical location data substantially matches the reference geographical location data of the first entity, the authorization message is generated. Thus, if a third party is in possession of the first entity's mobile device and attempts to participate in an electronic transaction outside the first entity's “registered location”, the electronic transaction is declined as the current geographical location data (e.g., Los Angeles) does not substantially match the reference geographical location data (e.g., New York).

A first of the two entities may consist of a single payer (e.g. a single individual) and a second of the two entities may consist of a single payee. In such a case, the electronic transaction comprises an electronic fund transfer from the single payer to the single payee. The electronic fund transfer may be a peer-to-peer (P2P) fund transfer or Electronic funds transfer (EFT).

Alternatively, a first of the two entities may consist of a single payer and a second of the two entities may consist of multiple payees. In such a case, the electronic transaction comprises an electronic fund transfer from the single payer to the multiple payees, and the facial image template relating to the second of the two entities and the second captured facial image data comprise facial image data of each of the multiple payees. Also, the account data relating to the second of the two entities comprises account data of each of the multiple payees. In an implementation, the funds from the single payer can be split equally among the multiple payees. Alternatively, the payer can specify the exact percentage or amount to be split among the multiple payees.

Alternatively, a first of the two entities may consist of a customer and a second of the two entities may consist of an employee of a merchant. In such a case, the electronic transaction comprises an electronic financial transaction between the customer and the merchant. If the merchant has multiple employees, each employee may be considered a separate entity, as will be explained in more detail below. In such a case, the method 100 may include the following steps to optimize the search, lookup or retrieval of facial image templates. At a first step, a geographical location of the transaction can be captured. For example, current geographical location data relating to a current location of the customer is captured by the customer's mobile device having a suitable location tracking module, and the current geographical location data is sent to the verification module. The second step involves a lookup of facial image templates of merchants located at the vicinity of the current geographical location based on the reference geographical location data of the merchant. For example, if the geographical location of the transaction is New York City, only the facial image templates of merchants located in New York City are looked-up. The third step involves authenticating the merchant based on the facial image templates that come as part of the look-up.

Embodiments described herein advantageously allow an electronic transaction to be carried out solely based on the provision of a photo of the entities involved in the electronic transaction. This is in contrast to current electronic transaction solutions, in which sensitive data may be required for the electronic transaction to be carried out, such as an entity's account details, account number, and name of bank, etc.

FIG. 2 shows a schematic diagram of a system 200 for authorizing an electronic transaction between two entities. The system 200 includes a verification module 202 and a database 204 in communication with the verification module 202. The database 204 can be realized using cloud computing storage modules and/or dedicated computer servers. Reference facial image data relating to each of the two entities and account data relating to each of the two entities are enrolled in the database. The facial image template and the account data of each entity are linked in the database, as described above.

The verification module 202 is in communication with a mobile device 206 through known wireless communication protocols/standards. The verification module 202 is configured to receive coincidentally captured facial image data relating to both of the two entities from the mobile device 206 and authenticate each of the two entities based on a comparison between the coincidentally captured facial image data and the respective facial image templates relating to each of the two entities. A positive authentication corresponds to a substantial match between the coincidentally captured facial image data and corresponding ones of the facial image templates.

The coincidentally captured facial image data comprises first captured facial image data relating to a first of the two entities and second captured facial image data relating to a second of the two entities. Preferably, the first and the second captured facial image data are captured at substantially the same time using the mobile device 206.

The verification module 202 is further configured to retrieve, from the database 204, the account data relating to each of the two entities based on the coincidentally captured facial image data, on determining that each of the two entities are positively authenticated. More specifically, the verification module 202 is configured to: retrieve the account data relating to the first of the two entities that is linked to the facial image template that has a closest similarity with the first captured facial image data; and retrieve the account data relating to the second of the two entities that is linked to the facial image template that has a closest similarity with the second captured facial image data.

The verification module 202 is further configured to generate an authorization message for authorizing the electronic transaction. The authorization message includes the account data relating to each of the two entities retrieved from the database. On the other hand, if at least one of the two entities is not positively authenticated, the verification module 202 is further configured to generate a decline message for declining the electronic transaction.

The substantial match between the coincidentally captured facial image data and the corresponding ones of the facial image templates may be based on a pre-defined degree of similarity between the first and the second captured facial image data and the corresponding ones of the facial image templates.

In an implementation, the verification module 202 is further configured to: receive a transaction identifier relating to the authorized electronic transaction; and store, in the database 204, the transaction identifier in association with the coincidentally captured facial image data relating to both of the two entities. Further, the verification module 202 may also be configured to receive, from the mobile device 206, a time-stamp relating to a date and time of the coincidentally captured facial image data; and store, in the database 204, the time-stamp in association with the transaction identifier and the coincidentally captured facial image data relating to both of the two entities.

In an implementation, the database 204 may further comprise reference geographical location data relating to each of the two entities and linked to the corresponding ones of the facial image templates. The verification module 202 may be further configured to: receive, from the mobile device 206, current geographical location data relating to a current location of the first of the two entities; and compare the current geographical location data and the reference geographical location data that is linked to the facial image template that has a closest similarity with the first captured facial image data. The authorization message is generated on determining that there is a substantial match between the current geographical location data and the reference geographical location data that is linked to the facial image template that has the closest similarity with the first captured facial image data.

The verification module 202 may be in communication with a payment module 208 that is configured to facilitate the electronic transaction between the two entities. The authorization message generated by the verification module 202 may be transmitted from the verification module 202 to the payment module 208 for authorizing the electronic transaction. The payment module 208 may also be configured to generate the transaction identifier upon completion of the authorized electronic transaction between the two entities and transmit the transaction identifier to the verification module 202.

FIG. 3 shows a schematic diagram illustrating flow of information between various entities during a registration phase of a method for authorizing electronic transactions between entities, according to an example embodiment. As described above, a first of the two entities may consist of a customer and a second of the two entities may consist of an employee of a merchant. In such a case, the electronic transaction comprises an electronic financial transaction between the customer and the merchant. A customer registration phase 300 begins with the customer (i.e., a first entity) initiating the enrolling process at step 302. The customer may use his mobile device to open a mobile application (“app”) or access a website for enrolling at step 304. The mobile application initiates a customer registration process 306, and subsequently activates an image capturing function of the mobile device at step 308. The customer is requested to take at least one photo of himself (in particular, his face). Preferably, at step 310, the customer is requested to take multiple photos of his face in various poses (e.g., smiling, winking, etc.) for added security.

The captured photo(s) are saved against the customer's profile at step 312. The customer's profile may include other types of data, such as the customer's account number. The captured photo(s) are used as references during authentication. Therefore, if at step 310, he winks in the photo(s), a third party trying to impersonate the customer (e.g., by presenting a stolen photograph of the customer in which he is not winking), is not able to easily succeed.

A merchant registration phase 350 begins with the merchant (i.e., a second entity) initiating the enrolling process at step 352. The merchant may use his computer to access a website for enrolling at step 354. The website or application initiates a merchant registration process 356, which subsequently activates an image capturing function of the computer at step 358. The merchant (or employee of the merchant) is requested to take at least one photo of himself (in particular, his face). Preferably, at step 360, the merchant is requested to take multiple photos of his face in various poses (e.g., smiling, winking, etc.) for added security.

The captured photo(s) are saved against the merchant's profile at step 362. The merchant's profile may include other types of data, such as the merchant's identifier, account number, and location. At step 364, if the merchant has more than one employee involved in transactions (e.g., cashiers), steps 358, 360 and 362 are repeated for all such employees. In the case of multiple employees, at step 362, the merchant's data, such as the merchant's identifier, account number, and location, remains unchanged. In other words, the plurality of captured photos are saved against the same merchant profile.

The customer registration phase 300 and the merchant registration phase 350 are typically performed once. After successful registration, the registration phases need not be repeated. The customer and merchant can now participate in electronic transactions, such as the ones described below.

FIG. 4 shows a schematic diagram illustrating flow of information between various entities during a method 400 for authorizing electronic transactions, according to an example embodiment. At step 402, a customer visits a merchant's physical store with the intention to purchase one or more products. At step 404, the merchant provides the complete price of the one or more products. The customer opens a mobile application (“app”) installed on his mobile device to initiate the authentication process at step 406.

At step 408, the mobile application activates an image capturing function of the mobile device. Preferably, the mobile device has two image capturing modules, in which the first image capturing module is a “front facing” camera of the mobile device and the second image capturing module is a “back facing” camera of the mobile device. The “back facing” camera is used to take a photo of the merchant while the “front facing” camera is used to take a photo of the customer. To facilitate the image capturing process of the customer and merchant, the user interface of the mobile application displays the images of the customer and merchant captured by the respective cameras in a split screen (i.e., the images of both customer and merchant are shown simultaneously on the screen of the mobile device).

At step 410, the image data relating to the images of both customer and merchant (i.e., coincidentally captured facial image data) is sent to a verification module with an integrated database via a network scheme for validation. At step 412, the verification module retrieves the merchant's profile based on the captured facial image data relating to the merchant. The verification module validates the customer based on the captured facial image data relating to the customer. In particular, the customer is validated or authenticated based on the reference photo(s) that were saved against the customer's profile at step 312 above. For example, the customer's captured facial image data is compared against all the customer reference photos registered in the database and a positive validation occurs if there is a pre-defined degree of similarity between the customer's captured facial image data and one of the reference photos.

For added security, validation or authentication of the merchant is performed at step 412. Firstly, the verification module validates the merchant based on the captured facial image data relating to the merchant. In particular, the merchant is validated based on the reference photo(s) that were saved against the merchant's profile at step 362 above. For example, the merchant's captured facial image data is compared against all the merchant reference photos registered in the database and a positive validation occurs if there is a pre-defined degree of similarity between the merchant's captured facial image data and one of the reference photos.

At step 414, further validation or authentication of the merchant may be performed by cross-checking the merchant's location. For example, the customer's mobile device may be configured to transmit a location of the customer to the verification module. Since the merchant is assumed to be at the same location as the customer, it follows that the merchant's location is expected to be the same as the transmitted location of the customer. The verification module cross-checks the transmitted location of the customer to determine whether it matches a reference location of the merchant stored in the database. For example, if the merchant's reference location is New York, and the transmitted location is not within New York City, a possible transaction fraud signal may be triggered. Similarly, a merchant's store name can be cross-checked by requesting that the customer enter the name of the merchant he is currently at. The name of the merchant can be transmitted to the verification module for cross-checking.

Assuming that the customer and merchant are positively authenticated at steps 412 and 414 above, the customer's information (including his account data) is retrieved from the database at step 416. Since the facial image template and the account data of each entity are linked in the database, the relevant account data can be retrieved.

At step 418, the merchant is informed (e.g., via a message transmitted to the merchant's point-of-sale terminal) that the customer has been authenticated. The merchant is requested to confirm that the transaction may proceed.

If the merchant confirms at step 418 that the transaction may proceed, step 420 is executed, which involves updating the relevant merchant information against the customer's purchase using the verification module.

To facilitate subsequent fraud or chargeback investigations, the image data relating to the images of both customer and merchant (i.e., coincidentally captured facial image data) is saved and encrypted in the database for record purposes, at step 422. An authorization response is provided to both the customer and merchant. At step 424, the merchant receives notification of the purchase and releases the one or more products to the customer. Likewise, at step 426, the customer receives notification of the purchase and receives the one or more products from the merchant.

FIG. 5 shows a schematic diagram illustrating flow of information between various entities during a method 500 for authorizing electronic transactions between entities, according to an example embodiment. As described above, a first of the two entities may consist of a single payer and a second of the two entities may consist of a single payee. In such a case, the electronic transaction and electronic fund transfer are from the single payer to the single payee. Alternatively, the second of the two entities may consist of multiple payees, and the electronic transaction comprises an electronic fund transfer from the single payer to the multiple payees.

At step 502, the payer opens a mobile application (“app”) installed on his mobile device to initiate the electronic fund transfer to the payee(s). At step 504, the payer selects an option to transfer funds to the payee(s) that may be provided on a user interface of the mobile application. At step 506, if there is more than one payee, the payer can have the option to split the transferred funds equally among the multiple payees or specify the exact percentage or amount to be split among the multiple payees.

Assuming that the payer and payee(s) are physically present at the same place and at the same time and facing each other, and a first image capturing module is a “front facing” camera of the payer's mobile device and a second image capturing module is a “back facing” camera of the payer's mobile device, the payer uses the “back facing” camera of his mobile device to capture a photo of the payee(s) and uses the “front facing” camera to take a photo of himself. In this manner, the mobile device acquires a coincidentally captured facial image data relating to both of the two entities at step 508.

At step 510, the coincidentally captured facial image data is transmitted from the payer's mobile device to a verification module having an integrated database. At step 512, the payee's/payees' account data are retrieved or determined based on the coincidentally captured facial image data on determining that the payer and payee(s) are positively authenticated (i.e., there is a substantial match between the coincidentally captured facial image data and corresponding facial image templates of the payer and payee(s)).

At step 514, the payee(s) approve the receipt of funds from the payer. At step 516, the funds are transferred from the payer to payee(s) via appropriate channels, e.g., peer-to-peer (P2P) fund transfers or Electronic funds transfers (EFT). Finally, at steps 518 and 520, the payee(s) and payer are informed of the successful fund transfer, respectively.

As an alternative to the method 500 described above, there is provided a method 600 for authorizing electronic transactions between entities, according to an example embodiment. A first of the two entities may consist of a single payer and a second of the two entities may consist of a single payee. In such a case, the electronic transaction and electronic fund transfer are from the single payer to the single payee. However, in contrast to method 600, the payee initiates the fund transfer by requesting to receive funds from the payer. The first of the two entities may consist of multiple payers, and the electronic transaction comprises an electronic fund transfer from the multiple payers to the single payee.

At step 602, the payee opens a mobile application (“app”) installed on his mobile device to initiate the electronic fund transfer from the payer(s). At step 604, the payee selects an option to receive funds from the payer(s) that may be provided on a user interface of the mobile application. At step 606, if there is more than one payer, there may be an option to have the transferred funds received from the multiple payers in equal proportions or based on a specific percentage or amount from the multiple payers.

Assuming that the payer(s) and payee are physically present at the same place and at the same time and facing each other, and a first image capturing module is a “front facing” camera of the payee's mobile device and a second image capturing module is a “back facing” camera of the payee's mobile device, the payee uses the “back facing” camera of his mobile device to capture a photo of the payer(s) and uses the “front facing” camera to take a photo of himself. In this manner, the mobile device acquires a coincidentally captured facial image data relating to both of the two entities at step 608.

At step 610, the coincidentally captured facial image data is transmitted from the payee's mobile device to a verification module having an integrated database. At step 612, the payer's/payers' account data are retrieved or determined based on the coincidentally captured facial image data on determining that the payer(s) and payee are positively authenticated (i.e., there is a substantial match between the coincidentally captured facial image data and corresponding facial image templates of the payer(s) and payee).

At step 614, the payer(s) approve the transfer of funds to the payee. At step 616, the funds are transferred from the payer(s) to payee via appropriate channels, e.g., peer-to-peer (P2P) fund transfers or Electronic funds transfers (EFT). Finally, at steps 618 and 620, the payee and payer(s) are informed of the successful fund transfer, respectively.
